Restoring a single maxillary incisor presents the greatest blend challenge with dentistry in the smile zone. When the adjacent teeth are in good shape, I stay conservative. With chairside CAD/CAM using the Dentsply Sirona system, the Copy and Mirror is my preferred design approach creating a "DNA form and shape" by copying the adjacent central. The next step is choosing the ceramic that blends best for the case. Since the ceramic and cement refractory behavior will change once cemented, so will the value and blend. In my blend theater, I prefer placing a transitional restoration that is machined with the projected ceramic and luting

Even with the multi zirconia options of Katana and ZirCAD Multi, in my hands, infiltration is the simplest and most efficient way to enrich the cervical zone color and modify cervical saturation needs. And with just one firing...sintering. This video will share material recommendations and methods.
The method works on all zirconia brands.
- ZirCAD LT Colouring liquids (very forgiving)
- Katana STML
- ZirCAD Multi

With zirconia, I use glaze and stain only for subtle highlight surface characteristics. For this process, Ivocolor by Ivoclar works well on all the zirconia brands, particularly the multi ones such as Katana STML, ZirCAD Multi, and the coming ZirCAD Prime. This video will demonstrate the zirconia preparation required for glaze addition and then glaze/stain applications creating subtle surface enhancements.

Finishing zirconia when it comes out of the milling unit is referred to as zirconia in the green state. There are a few steps that can be taken to really improve the surface quality of the green zirconia, and once sintered will save finishing time. The technique in this video is applicable to the zirconia brands in our CEREC clinical theater (ZirCAD LT, ZirCAD Multi, Katana STML, CEREC Zirconia, and InCoris).

Texturing and luster polishing a ceramic or composite will create the finishing touch for restorative blend harmony. Each case is often unique. In CAD/CAM e.max dentistry, we shape and texture before crystallization. This works most of the time, however, occasionally when fitting the ceramic in the mouth, further texture and shape tweaking are desired. This video will review the burs and polishing for providing texture and luster polish on a crystallized e.max restoration.

One advantage of aesthetic multi-gradient zirconia like Katana STML, ZirCAD Multi, and ZirCAD Prime is the ability to polish and blend right out of the sintering furance. This video will provide the steps for post sintered aesthetic zirconia polishing using the JK04 using the Meisinger Zirconia Polishing Lab Kit.

Katana STML is the first of the available chairside multi-gradient aesthetic zirconia options for chairside CEREC milling. The sintering time in the Sirona SpeedFire furnace is in the 18:00-minute range. This is an incredible fact! A significant advantage for a multi zirconia application is that the aesthetic gradient is already in the pre-milled block. All we do is choose the matching color shade, mill, and polish after sintering. This video will demonstrate the effective finishing steps for Katana STML using the Klim Institute Meisinger Zirconia Lab Kit JK04.

This video shares my passion for why I love providing online CEREC education. I have been so blessed by making a decision 15 years ago to integrate CEREC into my clinical theater. Fast forward to the latest Primescan! It is hard to believe how this restorative digital journey has evolved to now impacting a significant part of my daily clinical chairside care.
- Restorative Restorations
- Implant Placement (Crown Down Technique)
- Implant Restorations
- Removable Appliances and Splints
- Comprehensive Restorative Care
- Restorative Implant Hybrid Prosthesis

This is the second part video for no prep veneers with CEREC. This video will emphasize how to set the case up and assure patient emotional closure for the no prep or minimal prep. It is good to understand the shade and shape limitations with a conservative approach and being able to identify those cases that will result in a successful outcome before the treatment is started.
